Product Details：

Honeywell 51197564200 (51197564-200) is the high-capacity upgraded memory expansion module for Honeywell TDC3000 HPM High Performance Process Manager rack,compatible with the 51197564100 memory board and matched with HPM dual-node processor board. Compared with the previous generation memory module,this version provides larger storage capacity to support more complex control strategies,multiple PID loops,interlock logic,sequence batch programs and extensive point database for heavy-load process control racks. It connects to the HPM backplane bus,real-time caching of sampling data uploaded from UCN IOP nodes,storing offline downloaded control configuration,alarm setting parameters and calculation formulas. It adopts independent battery backup circuit for memory array,protecting all stored configuration and historical event records when the rack AC power supply loses power,avoiding the trouble of re-downloading all control programs after power failure recovery. It supports redundant HPM rack deployment scheme,keeping real-time data synchronization between primary and standby memory modules to realize bumpless transfer without interrupting production control. It optimizes internal data check and synchronization logic,reducing memory parity error and synchronization frame loss under large data throughput. It continuously monitors memory read-write status,backup battery voltage,backplane bus communication and node synchronization signals,records timestamped fault logs and uploads low battery,memory parity or synchronization failure alarms to LCN operator stations for maintenance personnel to replace battery or module. It supports hot swap operation under lockout-tagout maintenance procedure to reduce the risk of interruption of critical continuous process control loops. It is a scarce original spare memory board for legacy TDC3000 HPM projects,matched with HPM CPU board,dual node power supply and NIM gateway module.

Key specifications：Rack plug-in high-capacity memory module for TDC3000 HPM chassis,battery-backed memory design,proprietary HPM backplane interface,upgraded storage density. Operating temperature range is 0°C to +60°C. It supports memory parity error,battery low voltage,synchronization loss and bus communication timeout fault diagnosis. The PCB is conformal coated for dust-proof and anti-surge performance. Front panel LED indicators display memory running state,active/standby synchronization status and fault warning for quick on-site inspection.

This HPM memory module is widely deployed in petrochemical,chemical,power generation and water treatment plants for legacy TDC3000 DCS HPM control rack upgrade and spare replacement projects. It cooperates with Honeywell NIM gateway,UCN coaxial cable and HM history module to build LCN+UCN distributed high-performance control architecture. As a core unit for high-capacity HPM memory and controller storage board,it is the large-capacity extended memory carrier for TDC3000 high-performance process manager rack. Clearly defined edge connectors simplify rack installation,configuration download verification and regular battery voltage inspection work for control engineers.
